z/OS V1R9.0 UNIX System Services Command ... - Christian Grothoff

Usage notes
_LD_SYSLIB
The system library data set concatenation to be used to resolve symbols.
The default value is:
" " (null)
_LD_SYSIX
The system definition side-deck list to be used to resolve symbols. A
definition side-deck contains link-editing phase IMPORT control statements
naming symbols which are exported by a DLL. The default value is
"" (null)
_LD_XSUFFIX
The suffix by which ld recognizes a definition side-deck file of exported
symbols. The default value is
"x"
_LD_XSUFFIXHOST
The suffix by which ld recognizes a definition side-deck data set of
exported symbols. The default value is
"EXP"
1. Messages generated from the use of the ld command are provided in z/OS
MVS System Messages, Vol 8 (IEF-IGD).
2. ld provides similar function to the link-edit step of the c89 command. It does
not provide any functions of the compile and assembly phases of c89, nor any
steps of the link-edit phase except for the link-edit step --ld merely calls the
program management binder. The other main difference is that c89 has default
settings that are designed for linking an object file produced by the IBM C/C++
compiler for execution in the Language Environment, whereas the default
settings of ld do not include compiler or environment assumptions, and it can
therefore be more easily used to link objects from other compilers or that are
destined for environments other than Language Environment.
You can use ld options, operands, or environment variables to cause ld to
create executable modules that are compatible with those c89 produces by
default:
Option/operand Environment variable Value for c89 compatibility
-e _LD_ENTRY_POINT CEESTART
or, for AMODE 64 code,
CELQSTRT
-O _LD_ORDER CEESTART
or, for AMODE 64 code,
CELQSTRT
-S _LD_SYSLIB //’CEE.SCEELKEX’:
//’CEE.SCEELKED’:
//’CBC.SCCNOBJ’:
//’SYS1.CSSLIB’
